edit: I realize there is Office web and it's good but it has nowhere enough features. Also, do you guys think (Open, Libre, Only) office has as many features as Microsoft Excel?

I am taking business studies this year and you really do need excel for that. I can obviously use OnlyOffice Suite which is quite good and will get most of the jobs done, but it's not equivalent to MS Office suite and in business you use what's used most frequently, so yes, MS Office it is. But as much as I realize what a key role Microsoft plays in the Business, I DO NOT WANT TO PAY for it and I certainly DO NOT want to pay a subscription for it, but I want to learn it and the best way to learn is by doing it, so, I want to install MS Office Suite on Linux without actually paying for it, so how can I do it?

Skip this rant: Every freaking thing is a subscription right now, I mean, there's positives to that, but you feel like you own nothing. Don't want to be a conspiracy theorist or anything, but it feels like every company took "You will own nothing and be happy" to heart. Again, subscription model has it's advantages, but I don't want to subscribe to something I know I am going to need for the foreseeable future.

I realize and understand the criticisms of ChatGPT and I have personally seem how bad it can be. Once I asked to count the number of days till a random date giving the present date and it failed miserably, again and again. Trust me! I get the criticism. But, what about Bing Chat Bot?

Have you ever tried to ask you Physics and Maths related questions to it? I was coding a while ago and I had a pretty complex questions which could not be solved by a very popular reddit coding community but Bing Chatbot gave an answer to it in an instant! I was genuinely impressed. Apparently it checks for answers on multiple webpages on the internet, it reads and understands what it reads and it gives the answer to it after combining the knowledge it gained from it's search. Again, the question I asked was pretty complex but it was able to answer it in an instant and it was the right answer! It was coding, it's pretty hard to get the right answer in the first try, I have found it's more "trial and error".

So yeah!

1. Can I rely partially on Bing Chatbot for math questions?
2. If not can I ask it to form a query which encapsulates my question perfectly?
3. If not, should I ask it to "Answer this question and site your sources"?
4. Can I do something more? i.e., like I did in 3? What are your thoughts on this?

I won't be able to reply to each of your comments anytime soon, but know that I deeply appreciate this community and it's members and their help :')
